The following describes the vehicle control method provided by the embodiment of the invention in detail with reference to fig. 1. Fig. 1 is a flowchart of a vehicle control method according to an embodiment of the present invention. As shown in FIG. 1, the vehicle control method provided by the embodiment of the invention comprises steps S11-S14.
A step S11 of, when the vehicle is in a state of being allowed to be controlled, determining whether or not the mobile terminal wirelessly communicating with the vehicle is in a stationary state;
after the wireless connection with the mobile terminal is established, whether the vehicle is allowed to be controlled or not can be judged according to the vehicle speed signal and the seat signal of the vehicle, and specifically, when the vehicle speed signal shows that the vehicle is at a standstill and the seat signal of the vehicle shows that no person is in the seat, the vehicle is in a state of allowing to be controlled. If the vehicle is in a state of being permitted to be controlled, step S12 is performed.
Before the vehicle is controlled, the vehicle is ensured to be in a state of being allowed to be controlled, so that a series of misoperation such as alarming, unlocking, welcoming and locking is avoided when the vehicle is used. In other words, the vehicle control method provided by the embodiment of the invention is used for ensuring that the vehicle is in an idle state when the vehicle control method is executed.
The embodiment of the invention can judge whether the mobile terminal is in a static state or not according to the sensor information of the mobile terminal, wherein the sensor information of the mobile terminal comprises gyroscope sensor information and acceleration sensor information, whether the mobile phone rotates or not is judged according to the gyroscope sensor information, and whether the mobile phone moves or not is judged according to the acceleration sensor information, so that whether the mobile terminal is in the static state or the motion state is judged. If the mobile terminal is in a stationary state, performing step S12, and if the mobile terminal is in a moving state, performing step S13.
And step S12, controlling the vehicle to execute alarm logic. Specifically, the controlling the vehicle to execute the alarm logic includes: and if the Bluetooth signal intensity of the mobile terminal is smaller than a first threshold value, controlling the vehicle to execute an alarm operation. Wherein the first threshold may be-90 db, and the alarm operation includes, but is not limited to: whistling or turning on the vehicle lights.
When the mobile terminal is in the static state, the position of the mobile terminal needs to be further confirmed so as to avoid the situation that although the mobile terminal is in the static state, the alarm operation is triggered when the mobile terminal is positioned outside the vehicle. Generally, the mobile terminal can be determined to be located in the vehicle when the Bluetooth signal strength of the mobile terminal is less than-90 db.
And step S14, judging whether to control the vehicle to carry out unlocking logic or locking logic according to the door lock signal of the vehicle.
Specifically, the method comprises the following steps: if the door lock signal of the vehicle shows that the vehicle lock is in a locked state, controlling the vehicle to carry out unlocking logic; and if the door lock signal of the vehicle shows that the vehicle lock is in an unlocked state, controlling the vehicle to carry out locking logic.
Through judging the door lock signal of vehicle, judge whether need carry out unblock logic or shutting logic, reducible mobile terminal physical key's use improves user experience.
Wherein, as shown in fig. 2, the unlocking logic comprises:
when an unlocking command sent by the mobile terminal is received, controlling the vehicle to execute an unlocking operation; and when the unlocking command sent by the mobile terminal is not received, judging whether the vehicle needs to be controlled to execute welcome operation or unlocking operation according to the Bluetooth signal intensity of the mobile terminal.
Further, judging whether the vehicle needs to be controlled to execute the welcome operation or the unlocking operation according to the Bluetooth signal intensity of the mobile terminal comprises the following steps: if the intensity of the Bluetooth signal of the mobile terminal is continuously increased and is increased to be larger than a second threshold value, determining that the vehicle needs to be controlled to execute an unlocking operation; and if the Bluetooth signal intensity of the mobile terminal is continuously increased and is increased to be larger than a third threshold value, determining that the vehicle needs to be controlled to execute the welcome operation. Wherein the second threshold may be-72 db, -68db, such as-72 db, -70db or-68 db, and the third threshold may be-89 db-85 db, such as-89 db, -87db or-85 db.
As shown in fig. 3, the latching logic comprises: when a locking command sent by the mobile terminal is received, controlling the vehicle to execute locking operation; and when the locking command sent by the mobile terminal is not received, judging whether the vehicle needs to be controlled to execute locking operation or not according to the Bluetooth signal intensity of the mobile terminal.
Further, the step of judging whether the vehicle needs to be controlled to execute the locking operation according to the bluetooth signal intensity of the mobile terminal comprises:
if the intensity of the Bluetooth signal of the mobile terminal is continuously reduced and is reduced to be smaller than the first threshold value, determining that the vehicle needs to be controlled to execute locking operation; if the intensity of the Bluetooth signal of the mobile terminal is continuously reduced and is smaller than a fourth threshold value, a locking request signal is sent to the mobile terminal to confirm whether the vehicle needs to be controlled to execute locking operation, and if a signal which represents that the vehicle agrees to locking and is sent by the mobile terminal is received after the locking request signal is sent, the vehicle needs to be controlled to execute locking operation. Wherein the signal indicating that the mobile terminal agrees to latch is sent by shaking the mobile terminal or tapping the screen of the mobile terminal. Likewise, user experience may be improved by avoiding the use of physical keys for validation. Wherein the fourth threshold may be-85 db.
Preferably, the flash lock logic further comprises: after controlling the vehicle to execute locking operation, judging whether the vehicle is locked or not according to a door lock signal of the vehicle; and if the vehicle does not complete locking, controlling the mobile terminal to vibrate and/or send out voice.
Inevitably, the situation that the lock is still in the unlocked state after the vehicle is controlled to be locked happens occasionally, and in the situation, the safety of the vehicle use can be improved by controlling the mobile terminal to vibrate and/or send out voice to remind a user.
In addition, before step S11, the vehicle control method provided in this embodiment may further include:
when a connection request of the mobile terminal is received, verifying the identity of the mobile terminal;
and if the verification is passed, establishing wireless connection with the mobile terminal.
Correspondingly, the embodiment of the present invention further provides a vehicle control system 1, including: the judging module 11 is configured to, when a vehicle is in a state of being allowed to be controlled, judge whether a mobile terminal in wireless communication with the vehicle is in a stationary state, if the mobile terminal is in the stationary state, control the vehicle to execute an alarm logic, and if the mobile terminal is in a moving state, determine whether to control the vehicle to perform an unlocking logic or a locking logic according to a door lock signal of the vehicle.
In conclusion, the vehicle control method and the vehicle control system provided by the invention solve the problems that the operation of unlocking the vehicle of the conventional PEPS system needs to be performed on a physical key, the operation is not convenient enough, and the function of reminding a user that a mobile terminal provided with an intelligent key is left in the vehicle is not provided.
